Abstract

The utility model relates to a clamp for cutting square silicon crystal rods. The clamp is divided into a bottom layer and an inner layer. The bottom layer is an L-shaped iron plate, the inner layer is an L-shaped PVC plate embedded in the inner wall of the bottom layer, a bottom saw kerf is formed in the same position of the bottom of the bottom layer and the bottom of the inner layer, and a side saw kerf is formed in the side portion of the inner layer and in the same position as the bottom saw kerf. By adopting the clamp, the square silicon crystal rods or quasi-square silicon crystal rods are placed in the L-shaped clamp, and a clamping device is not needed; a saw blade cuts downwards to generate an acting force, a cut-off machine platform moves horizontally towards the direction of the saw blade at a constant speed to generate an acting force, the square silicon crystal rods or the quasi-square silicon crystal rods are firmly attached to the interior of the L-shaped clamp and then cut and divided under the two acting forces, and operation is convenient, fast, safe and reliable; the crystal rods are convenient to pick and place.

Description

A kind of cut-out silicon wafer square rod fixture

Technical field

The utility model relates to a kind of cut-out silicon wafer square rod fixture.

Background technology

At present, conventional crystal bar cutting machine fixture is V-shaped, generally all for the round monocrystal rod of cutting, designs, very inapplicable for square or accurate square polycrystalline cast ingot, can not normally cut at all.

Summary of the invention

The purpose of this utility model is to provide can convenient, fast square shaped or the accurate square a kind of cut-out silicon wafer square rod fixture cutting off.

The technical scheme that the utility model is taked is: a kind of cut-out silicon wafer square rod fixture, it is characterized in that it is divided into two layers of bottom and internal layers, bottom is L-type iron plate, internal layer is the PVC plate that is embedded in the L-type on bottom inwall, and at same position place, the bottom of bottom and internal layer, have bottom saw kerf, on the sidepiece of internal layer and with saw kerf same position place, bottom, have sidepiece saw kerf.

Adopt the utility model, silicon wafer square rod or accurate square rod are put into L-type fixture, do not need clamping device, at saw blade, cut under the active force of generation downwards and cutting machine platform under the active force of blade direction uniform translation, silicon wafer square rod or accurate square rod can be attached to firmly in L-type fixture and be cut off and cut apart, convenient, fast and safe and reliable, crystal bar picks and places also very convenient.

Accompanying drawing explanation

Fig. 1 is schematic diagram of the present utility model;

fig. 2 is schematic side view of the present utility model.

In figure, sequence number represents: iron plate 1, PVC plate 2, bottom saw kerf 3 and sidepiece saw kerf 4.

The specific embodiment

Below in conjunction with specific embodiment, the utility model is described in further detail.

With reference to Fig. 1, this cut-out silicon wafer square rod is divided into two layers of bottom and internal layers with fixture, bottom is L-type iron plate 1, internal layer is the PVC plate 2 that is embedded in the L-type on bottom inwall, and at the same position place, bottom of the iron plate 1 of bottom and the PVC plate 2 of internal layer, have bottom saw kerf 3, on the PVC of internal layer plate 2 sidepieces and with bottom saw kerf 3 same position places, have sidepiece saw kerf 4.During use, silicon wafer square rod or accurate square rod are put into this L-type fixture, do not need clamping device, at saw blade, cut under the active force of generation downwards and cutting machine platform under the active force of blade direction uniform translation, silicon wafer square rod or accurate square rod can be attached to firmly in L-type fixture and be cut off and cut apart, convenient, fast and safe and reliable, crystal bar picks and places also very convenient.

Claims

1. one kind is cut off silicon wafer square rod fixture, it is characterized in that it is divided into two layers of bottom and internal layers, bottom is L-type iron plate, internal layer is the PVC plate that is embedded in the L-type on bottom inwall, and at same position place, the bottom of bottom and internal layer, have bottom saw kerf, on the sidepiece of internal layer and with saw kerf same position place, bottom, have sidepiece saw kerf.
